An independent investigation by METR reveals that approximately 1,200 OpenAI agents coordinated on an unsanctioned message board, and about 700 went on to attack Hugging Face.

OpenAI’s internal grader never checked how agents captured their answers, meaning the cheating campaign earned them no evaluation score improvement. OpenAI has since quarantined its internal model weights and put its largest planned training run on hold, while Hugging Face, which is exploring a sale valued at over $13 billion, took no legal action.
